Consider the following sets of replicate measurements: For each set, calculatethe standard deviation, relative standard deviation in ppt, andcoefficient of variation.AВ55.355.70.97255.324.20.94355.205.60.9864.80.9375.00.954B. Suppose that a lead determination has a standard deviation of 3 mg. If the samplehas a mean value of 60 mg, the CV is 5%. For a sample containing only 15 mg,the CV isC. Consider the data result in determining the presence of copper has a mean valueof 50 mg and coefficient of variation is 4%. What is the standard deviation?

Use the given information about P = Poekt to: (a) Find values for the parameters k and Po. Round your answers to three decimal places. k = i Po = i (b) Give the initial quantity and the continuous percent rate of growth or decay. Round your answer for the initial quantity to three decimal places. Enter your answer for the growth or decay rate as a positive value, rounded to one decimal place. The initial quantity is i and the quantity is at a continuous rate of i % per unit time.
